The first roadway 1 is used for placing a guniting machine 3 and transporting guniting materials; the second roadway 2 is a roadway needing guniting. The first roadway 1 and the second roadway 2 are opened through drilling operation, the guniting pipe 4 penetrates into the pipeline drilling hole 6, the guniting machine 3 is fed to operate on one side of the first roadway 1, and guniting is carried out on the spraying sites in the second roadway 2 through the guniting pipe 4 in the pipeline drilling hole 6. The spraying mode saves the time of paving tracks on the working face, transporting the spraying machine and transporting the spraying slurry, and improves the spraying operation efficiency of the working face.
In an exemplary embodiment, the guniting apparatus further comprises: the track 8 is arranged in the first roadway 1, and the track 8 is used for transporting guniting materials to the guniting machine 3 for use.

In an exemplary embodiment, the sleeve is a rigid plastic or metal tube. The sleeve is used for supporting, so that the sleeve is selected to be a hard plastic pipe or a metal pipe, and the metal pipe can be selected to be a steel pipe or an aluminum alloy pipe; the hard plastic is named PPS, namely polyphenylene sulfide, which belongs to a novel high-performance thermoplastic resin, and is a special engineering plastic with excellent comprehensive performance, and has the advantages of high temperature resistance and corrosion resistance, good physical and mechanical properties and stability.
In an exemplary embodiment, the guniting apparatus further comprises: and the controller is arranged in the second roadway 2 and is connected with the guniting machine 3.
